The speed input range of the Advance HCD600A marine gearbox is 1000-2100 RPM, with engine input power from 903 kW to 1029 kW. the center distance is 415 mm, the reduction ratio range is 4.18-5.71, the transmission capacity range is 0.43-0.49 kW/RPM, the rated propeller thrust is 90 KN, and the input shaft is in the train Opposite to the output shaft.
Advance HCD600A marine gearbox is composed of transmission shaft, output coupling, input coupling, oil pressure gauge, oil Filter, control system, oil pump and other important components.
Advance HCD600A marine gearboxes provides three types of control system which are push-pull flexible shaft, electric control and pneumatic control for customers to choose. To meet the different requirement of coupling with different engine brand and models, Advance HCD600A marine gearboxes provide different SAE size coupling and housing including SAE 00 0 1 Without, flywheel SAE 21 18 16 14 is available……
All of our Advance 600 series marine gearbox can provide CCS classification certificate, some of series can provide international classifications with extra costs which mainly including French BV, British LR, American ABS, Japanese NK , Norway DNV-GL, Russia RS, South Korea KR, Italy RINA and other classification societies.
Advantages Of Advance HCD600A Marine Gearbox Parts
Advanced design and sophisticated manufacturing to adapt to various harsh working conditions! High-strength parts, strong ability to work under heavy loads.
Cylinder block and cylinder head adopt integrated design. The occurrence of engine water leakage and oil leakage is prevented, and the parts are about 40% less than other similar engines. The failure rate is greatly reduced.
Using forged steel camshaft and crankshaft, high-strength cylinder block design, multiple parts cast on the cylinder block, high rigidity, high pressure resistance, good reliability, and longer service life.
The cylinder bore adopts a platform mesh honing design. The perfect geometric structure effectively prevents oil leakage, and the use of advanced technology such as new piston ring components and gasket crimping and molding reduces oil loss.
The five key systems of the electronically controlled engine are all developed by DCEC, and have been applied and verified in different fields around the world to ensure the excellent economy and reliability of the product.
By optimizing the control strategy and combining with the actual operating conditions of the equipment, the fuel economy can be further improved.
